There is no designer fragrance that Curve could be considered a dupe of. This is a stand alone scent, that is very affordable, and would be considered a great starter budget fragrance. The original Curve (slightly similar in profile) was a huge scent for me back in the 90s. So, the appreciation I have for this cologne is certainly based on nostalgia. Be that as it may, I do believe that Curve Black is a solid fragrance.
